PRODUCT DATA SHEET
625 CXF
Corrosion Resistant, Extreme Pressure Grease-Food Grade
Description Superior resistance to washout by water, caustics, sanitizing cleaners, process fluids and steam has been combined with high purity USP White Mineral Oil to produce Chesterton® 625 CXF suitable for Food, Beverage and Pharmaceutical use. As a premium quality, water resistant grease, 625 will not be removed even in severe water washout situations. With a dropping point of 318°C (604°F), it will not melt and run out within recommended operating parameters. 625 is NSF Registered H1 and complies with FDA regulations 178.3570. It can be the exclusive lubricating grease used in food, beverage, meat, poultry and pharmaceutical plants. Chesterton 625 CXF is virtually nonstaining. Grease stains on floors and packaging equipment can be substantially reduced. Use 625 to lubricate packaging machinery and paper converting equipment. Chesterton 625 CXF is essentially tasteless and odorless. It is ideal as a maintenance or production lubricant used in food processing equipment, mixing, filling, packaging and production machinery. Chesterton 625 contains no animal fats or oils which could become rancid and support biological growth. Further, it contains no heavy metals which could mandate hazardous warnings and restrict use.
Composition Chesterton 625 is made using the highest quality, USP grade white mineral oil base stock available. Selected synthetic polymers and base oil are thickened with a proprietary, patent protected, sulfonate complex thickener. Anti-oxidant, extreme pressure (EP) and anti wear (AW) additive package gives Chesterton 625 superior washout resistance, shear stability, fatigue and anti-wear properties. Fortification with microscopic dispersion platelet-like particles of polar and non-polar lubricating additives benefits to Chesterton 625 CXF on several accounts:

ISO/DIN Classification
■ Enhances Lubricity — low coefficient of friction translates to better lubricity, less machine wear. ■ Increases load carrying capacity — Micron sized additives fuse to the surfaces and help protect machinery under extreme pressure. ■ Adds another safety factor as they will provide temporary lubrication in the event of grease burn off.
